A guide to a textbook-free approach to world languages curriculums that will improve learning outcomesOpen architecture curricular design (OACD) is a textbook-free curricular design framework for teaching and learning world languages that integrates all the best practices in world language education to enhance learning efficiency and effectiveness. As editors and pioneers of this method, Corin, Leaver, and Campbell define OACD for world language instructors and second language acquisition researchers from middle school through higher education and beyond. The book's chapters demonstrate how to use OACD for a wide variety of languages and proficiency levels in government, service academy, and university programs. Topics covered include the use of authentic texts at all levels, learner involvement in the selection of content and activities, and methods of assessment and program evaluation.
